| 1 | Food-Contact Compliance | Packaging materials should comply with the food-contact rules of the destination market, such as applicable U.S. or European requirements. | Declaration of compliance, material composition, migration test reports, and ink or adhesive compliance statements. | 15% | Reduces customs, safety, and regulatory risks when importing food packaging. |
| 2 | Food-Safety Management | A documented food-safety management system based on recognized international requirements, hazard analysis, and traceability. | Valid food-safety certificate, audit report, hygiene procedures, corrective-action records, and traceability exercise. | 12% | Flour is a food product, so contamination control and lot traceability are essential. |
| 3 | Material Structure | The film structure should match the flour’s sensitivity to moisture, oxygen, light, abrasion, and the required shelf life. | Complete layer structure, thickness, resin or paper specifications, coating details, and technical data sheet. | 12% | Correct material selection helps prevent moisture uptake, tearing, leakage, and product spoilage. |
| 4 | Moisture and Oxygen Barrier | Barrier performance should be specified by measurable water-vapor and oxygen transmission values rather than by general claims. | Laboratory reports showing WVTR and OTR, including test method, temperature, humidity, and sample thickness. | 12% | Flour quality can deteriorate when packaging allows excessive moisture or oxygen transmission. |
| 5 | Seal Integrity | Consistent heat-seal performance with suitable seal strength, clean seal areas, and no channels or pinholes. | Seal-strength test, leak test, burst test where applicable, production samples, and seal-temperature window. | 10% | Reliable seals protect the product during filling, transport, storage, and retail handling. |
| 6 | Dimensional and Printing Quality | Controlled pouch dimensions, registration, color consistency, print adhesion, and barcode readability. | Approved artwork proof, color standard, dimensional inspection report, rub test, and barcode verification. | 8% | Stable dimensions improve filling-line efficiency and reduce rejected or unreadable packages. |
| 7 | Production Capacity and Lead Time | The supplier should demonstrate sufficient converting capacity, realistic lead times, backup equipment, and raw-material planning. | Capacity statement, standard production schedule, sample-to-mass-production timeline, and on-time delivery records. | 10% | Supports reliable replenishment and reduces supply interruptions during seasonal demand. |
| 8 | Minimum Order Quantity and Cost Transparency | Pricing should clearly separate tooling, cylinders or plates, materials, printing, packing, inspection, and delivery terms. | Itemized quotation, MOQ by size and structure, tooling ownership terms, payment conditions, and validity period. | 8% | Transparent costing improves landed-cost calculations and prevents unexpected charges. |
| 9 | Quality Control and Traceability | Each production lot should be identifiable through raw materials, processing records, inspection results, and shipment documentation. | Quality-control plan, certificate of analysis, retained-sample policy, lot coding, and complaint-handling procedure. | 8% | Makes nonconformance investigation, recalls, and corrective actions faster and more controlled. |
| 10 | Export Service and Sustainability | The supplier should support export packaging, shipping documents, recycling information, and material-reduction options where technically suitable. | Packing specification, export references, shipping document samples, recyclability statement, and downgauging assessment. | 5% | Improves logistics execution and helps buyers meet changing packaging and environmental requirements. |
